Description

  The present invention relates to a ventilation direction control device suitable for ventilating inside and outside a building and inside a building, and a building including the same.

  In recent windows in buildings, the building walls are double walls or glass shojis are doubled and a hollow layer (air layer) is provided between them, and this hollow layer is used as a heat insulating layer to change the temperature of the outside air. Attempts have been made to prevent the temperature inside the building from being affected and to reduce the energy consumption for maintaining the temperature inside the building. Irradiation of double-wall or double-glass shoji with sunlight significantly raises the temperature of the air in the hollow layer, causing the air in the hollow layer to exceed the ambient temperature, increasing the load on cooling in the building and increasing energy consumption. In recent high-rise buildings, the windows cannot be opened or closed to prevent dangers, so the outside air is kept at the proper temperature and humidity. Nevertheless, air conditioning including air conditioning is performed on the building. The energy consumption due to this is enormous, and such air conditioning circulates air in the building, so that once the air is contaminated with bacteria, an undesirable situation occurs. There is.

Further, by closing the other opening with the opening / closing plate member, the hollow layer and the interior of the building can be communicated, and the hollow layer can be used as a passage for ventilation or air conditioning. For example, in the summer season, the air in the hollow layer can be prevented from exceeding the outside air temperature and the load on the cooling in the building can be reduced. As a result, energy saving can be realized, and When the layer is used as an air conditioning passage, for example, a hollow layer is used in winter. As a result of using warmed air for heating, energy saving can also be realized, and for example, one opening is closed by an opening / closing plate member, while another opening and another opening are opened. Because it can introduce outside air into the building or exhaust the air inside the building to the outside air, not only can clean the inside of the building with fresh outside air, but also can use a rectangular opening and closing plate member, Such an opening / closing plate member can be easily formed from a plate body, and cost can be reduced.

Clutch groove 79 (see FIG. 5) extending in a direction intersecting with the clutch plate 77 in this example, and a guide groove 78 and a clutch groove provided on the clutch plate 77 and rotating in the R1 and R2 directions of the clutch plate 77. 79 has a clutch engaging member 80 which is received alternately.

  The shaft 75 passes through a through hole 85 formed in the clutch plate 77 and is fitted into the through hole 38 of the connecting portion 39, and the clutch groove 79 is formed on the inner surface 70 of the side wall 15 together with the guide groove 78. The clutch engaging member 80 is attached to a shaft 87 fitted in a through-hole 86 formed in the clutch plate 77, is rotatably attached to the shaft 87, and the clutch plate 77 is rotated in the R1 and R2 directions. And a roller 88 that is alternately received in the guide groove 78 and the clutch groove 79.

  When the engagement projection 74 at the other end of the chain body 61 is located outside the slit 76 and the slit 76 does not receive the engagement projection 74, the clutch plate 77 is caused by its own weight, as shown in FIG. When the slit 76 receives the engaging protrusion 74 at the other end of the chain body 61 while the roller 88 is received in the clutch groove 79 by the rotational moment in the R2 direction due to the spring that is not As shown in FIG. 5, the roller is moved from the clutch groove 79 to the guide groove 78 by the rotational moment in the R1 direction due to the traveling of the engaging projection 74 in the A1 direction against the rotational moment in the R2 direction by its own weight or by a spring (not shown). The second rotation state is set so that 88 is shifted.

  The traveling unit 11 rotates the sprocket wheel body 67 through the rotation shaft 66 by the rotation of the output rotation shaft by the operation of the electric motor 51, and the chain body 61 engaged with the sprocket wheel body 67 by the rotation of the sprocket wheel body 67. Traveling in the A1 and A2 directions, the chain body 61 travels in the A1 and A2 directions, and the opening / closing plate member 9 travels in the A1 and A2 directions synchronously with the travel of the chain body 61 in the A1 and A2 directions via the shaft 62. On the other hand, when the engagement protrusion 74 is located outside the slit 76, the engagement protrusion 74 is caused to travel in the A1 direction by the travel of A1 of the chain body 61 due to the rotation of the output rotation shaft by the operation of the electric motor 51. The engagement protrusion 74 is received in the slit 76 by the travel of the engagement protrusion 74 in the A1 direction, and the engagement protrusion 74 is moved to the slit 76.

When the member 10 travels in the A1 direction and, conversely, the engagement projection 74 is received in the slit 76 and the clutch plate 77 is rotated in the R1 direction, the rotation of the output rotation shaft by the operation of the electric motor 51 is performed. When the chain main body 61 travels in the A2 direction, the engagement protrusion 74 travels in the A2 direction, and when the engagement protrusion 74 travels in the A2 direction, the clutch plate 77 engaged with the engagement protrusion 74 travels in the A2 direction. When the latch plate 77 travels in the A2 direction, the opening / closing plate member 10 travels in the A2 direction via the connecting plate 36, and the roller 88 moves from the guide groove 78 to the clutch groove 79 while the clutch plate 77 travels in the A2 direction. Then, the clutch plate 77 is rotated in the R2 direction to set the clutch plate 77 to the first rotation state, and the clutch plate 77 is engaged by setting the clutch plate 77 to the first rotation state and traveling the engagement protrusion 74 in the A2 direction. The engagement of the engagement protrusion 74 with the clutch plate 77 is released when the protrusion 74 comes out of the slit 76, and thus the traveling means 11 causes the opening / closing plate member 10 to be partially asynchronous with the travel of the chain 52 in the A1 and A2 directions. The chain 52 is directly connected to the open / close plate member 9 and is connected to the open / close plate member 10 via a clutch mechanism 54 so that the open / close plate members 9 and 10 are driven in conjunction with each other.
